Functional Requirements

    Just what they sound like, functional requirements define the information required in order to complete a particular process or work step for user. The list below identifies all the possible information we would like to consider for a basic user account, with the required information identified in red. This information might be collected over time or in several steps, as defined in the sequence diagram. Of course, on a big project, there could be hundreds or even thousands of functional requirements. One of the important design steps is to correlate all functional requirements, in order to efficiently store information, and to insure that all data has one master source — you don't want two users with two IDs and the same social security number, for instance.
